Find the period and amplitude y 12 sin x4 period amplitude

Find the period and amplitude. y = 1/2 sin x/4 period amplitude Find the period and amplitude. y = 9/2 cos x/3 period amplitude Find the period and amplitude. y = -cos 2x/3 period amplitude Find the period and amplitude. y = 2 sin x period amplitude Find the period and amplitude. y = 1/9 sin 4x period amplitude Find the period and amplitude.

Solution

9. amplitude=1/2, period=2pi/(pi/4)=8

10. amplitude=9/2 period=2pi/(pi/3)=6

11 Amplitude=-1 Period=2pi/(2/3)=3pi

12 Amplitude=2 Period=2pi/16=pi/8

13 Amplitude= 1/9 Period=2pi/4=pi/2
